Problem with Editing/Advanced/Delete/Cancel button on Quick Edit for Posts

[itsRahul]

I've upgraded to 4.2.2 successfully, but now am getting some errors. I've looked around, again, but I can't seem to find a good solution.

In every page, I get 2 warning errors:

Warning: Non-static method THANKS_CACHE::init() should not be called statically, assuming $this from incompatible context in ..../dbtech/thanks/hooks/global_start.php on line 9

Warning: Non-static method STATUS_CACHE::init() should not be called statically, assuming $this from incompatible context in ..../dbtech/status/hooks/global_start.php on line 9

At AdminCP I get the warning errors plus:

Unable to add cookies, header already sent.
File: /home/content/94/9082694/html/forum/includes/class_core.php
Line: 5745

So I added the DISABLE HOOKS line in my config.php, which lets me get to the forums and admincp. My edit post ajax problem seems to be fixed. But there's a bunch of notices about outdated templates and failed merges, and I still have the errors related to global_start. Do I need to reinstall plugins one by one to fix this? I've seen other people's similar problems with 4.2.2, but I'm not sure how to resolve this.
